Sierra Nevada, the private company that builds the spaceplane, has chosen the Vulcan rocket as its ride into orbit.
Neither the Dream Chaser vehicle, nor the Vulcan rocket, has yet flown to space.
Sierra Nevada was recently awarded the contract by Nasa to re-supply the ISS.
Under its Nasa contract, Dream Chaser has to fly a minimum of six missions to the ISS.
Sierra Nevada Corp competed for the Nasa contract to send astronauts to the ISS, under the agency's Commercial Crew Program.
